One of the low temperature ultrahigh vacuum scanning tunneling microscope (STM) of the LT-UHV 4-STM has been used to study binaphthyl-dimer molecules on Au(111) [1],[2]. The molecule has three C2 symmetry conformations energetically possible, namely, cis, trans, and planar-like conformations. Right after the molecules deposition on a clean gold surface, only cis conformation molecules forming small 2D islands have been observed. Using a STM tip single molecule mechanical manipulation protocol, single planar conformation molecules have been produced one by one corresponding to our registered nano-car. This confirms that on an Au(111) surface, single and isolated binaphthyl-dimer molecules equipped with 2 paddles are ready to compete for the first international nano-car race in Toulouse, spring 2017.
